I cannot load the Saturn version of Castelvania Symphony of the night in RetroArch on the Xbox One. I was able to load the game with RetroArch on Windows 10 and on PsVita (same rom and same bios). I used the yabause, yabasanshiro and the bettle saturn cores without any success, on the Saturn dashboard the disk is not recognised, or I can see the only audio 2 tracks. I tried Sonic Racing EU version and it worked.
Could you please let me know if you have any similar issue with this game or with any other Japanese games?
